It is a more complex filter than that: the change in HF is just what we measure to detect it. Clinically, one never looks at transients, for example, though it is likely that the fundamental mechanism affects them too, for what you lose in the broadest terms (at least the neural component) is dynamic range per unit time. It is striking, for example, that speech comprehension in conditions of noise is affected even when the measured HF attenuation is only just within the reported frequency window of speech. I don't know if anyone has studied it properly but I suspect it is precisely because you lose the capacity to deal with the fast non-stationarities that are characteristic of speech.
